We all know the feeling of coming home into a cold room or apartment, or coming home to find out that you left the radiator on all day or night. With this Smart Radiator Control you never have to worry about if you left the radiator on. Thermostat: Simply replace your existing radiator knob with this Smart Radiator Control and the built-in self-learning thermostat opens and closes the radiator as far as needed to keep the room at the desired temperature. Schedule and remote control: After installing it in the Nedis SmartLife app (using a Nedis Zigbee Gateway: WIFIZBxxx). You are able to set up a schedule to plan when the radiator needs to heat up a room. Make a weekly or a daily schedule, or just use your smart phone to set the temperature, wherever you are. Voice control: By combining it with Google Assistant or Amazon Alexa you can simply use your voice to change the target temperature in the room. Or set scenes in the Nedis SmartLife application that can be activated with a single push of a button, or by a single Siri shortcuts/Google/Alexa command. Physical control: On top of all these smart options you can also monitor the temperature on the LED display or intuitively rotate the front to change the desired room temperature, or simply press it to set the temperature to preset levels. A child lock can be activated to prevent undesired temperature changes. Sensors: Based on the temperature changes in the room the Smart Radiator Control can be set to recognize if a door or window is left open for a longer period of time, it will than automatically switch off the radiator. If no hot water is available (e.g. if the central heating is switched off) it will also be recognized and act accordingly. Control multiple radiators at once so you will never again forget a single room. By combining this product with other Nedis SmartLife products (such as the Zigbee door/window sensor or climate sensor) you can setup more accurate and energy efficient systems. Installation: Nedis Zigbee Gateway (WIFIZBxxx) is required for installing this product to the Nedis SmartLife application (Android / iOS). There are no special skills or knowledge (electrical or plumbing) needed for installation. You only need a screwdriver to remove your existing radiator knob and 2 AA batteries to power the Smart Radiator Control, also Hot water needs to be available for the radiator to work, so if your house has central heating, it is important that it is switched on.
